Interaction between different protein levels in the diet and infection with Haemonchus placet in calves under tropical condition.

Haemonchosis in cattle represents one of the biggest problem in Brazil, where an wide variations in dietary protein can be observed in pastures throughout the year. It is thought that this variation in protein intake might have influences on the impact of the parasite host metabolism arid productivity. This experiment was conducted to investigate the influence of dietary protein and the infection with Haemonchus placet upon parasitological parameters in growing calves.
